Cable Management Procedures
Sound cable management practices help data centers function smoothly and reliably. Managers can implement a variety of procedures to minimize data center inefficiencies, such as slow troubleshooting and interruptions due to the unplugging the wrong equipment.) Well managed cable supports server performance and throughput, minimizes disruptions and downtime, and safeguards the integrity of cables and ports.
One solution for complex networks is the use cable management systems (CMSs). There are many products and services available that managers can use to document cable sub-systems and paths, plan migrations and expansions, and track moves, adds and changes (MACs). The software requires manual entry of cable connections and types, and users must make updates for each move or change to keep documentation accurate. Some CMSs can model data center equipment and migrations and generate task lists for migration.
Horizontal and Vertical Management
Where Main Distribution Areas (MDAs) connect to Horizontal Distribution Areas (HDAs) and then to Equipment Distribution Areas (EDAs), managers need to deploy sturdy, reliable components that support high density, are easy to install, provide adequate spacing between ports, and can handle heavy cable bundles. The horizontal cable manager units are made of metal or heavy plastic. Choose pieces that are best-suited for the cable types and quantities within each rack. Dust covers are appropriate if there is little likelihood of MACs but can get in the way during re-cabling.
When choosing vertical management components, plan for ease of access and allow room for both patch cable slack and future increases in cable density. Use vertical and horizon- tal components that allow for acceptable bend radiuses, so that cables and ports are not damaged over time.
Network or telecommunications cabinets can simplify monitoring and troubleshooting by making switches and patch panels easy to view. Cabinets come in different heights (typically 6U to 15U) to accommodate multiple layers of 19-inch equipment and are wall-mounted to support heavy equipment. They typically include the wall-mount section and the cabinet itself, which is attached to the wall mount and has a Plexiglas front that allows monitoring without opening the cabinet. Doors are reversible to improve usability in tight spaces.
When setting up a cabinet, installers should populate the bottom sections first and add panels upwards from there. There should be sufficient openings to enable airflow, and fans should be added as needed. Locking options are available for secure installations, and there are options to add shelves and/or drawers.
